Primary Mathematics 1–6

Primary Mathematics is the original math curriculum that put Singapore at the top of international math tests. This renowned series has two decades of proven results in the U.S.

Primary Mathematics epitomizes what educators love about the Singapore math approach, including the CPA (Concrete, Pictorial, Abstract) progression, number bonds, bar modeling, and a strong focus on mental math. It is a rigorous program that balances supervised learning and independent practice while encouraging communication.

Please note that Primary Mathematics is not for sale to customers outside of the USA and Canada.


All three editions maintain the integrity of the Singapore math approach while serving diverse needs.
